This new Hubble image, captured and released on April 19, 2013 by the ESA-NASA Hubble Heritage to celebrate the telescopeâ€™s 23rd year in orbit, shows part of the sky in the constellation of Orion (The Hunter). Rising like a giant seahorse from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33. This image shows the region in infrared light, which has longer wavelengths than visible light and can pierce through the dusty material that usually obscures the nebulaâ€™s inner regions. The result is a rather ethereal and fragile-looking structure, made of delicate folds of gas â€” very different to the nebulaâ€™s appearance in visible light.== RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / NASA, ESA, and the Hubble Heritage Team (STScI/AURA)" - NO MARKETING - NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS ==HO/AFP/Getty Images less

In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star. Each appears in a different hue - red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula.

Arp 147 contains the remnant of a spiral galaxy (right) that collided with the elliptical galaxy on the left. This collision has produced an expanding wave of star formation that shows up as a blue ring containing in abundance of massive young stars. These stars race through their evolution in a few million years or less and explode as supernovas, leaving behind neutron stars and black holes.

Now for some earlier image of Orion

NASA's Spitzer and Hubble Space Telescopes teamed up to expose the chaos that baby stars are creating 1,500 light years away in a cosmic cloud called the Orion nebula. This striking composite indicates that four monstrously massive stars, collectively called the "Trapezium," at the center of the cloud may be the main culprits in the Orion constellation, a familiar sight in the fall and winter night sky in the northern hemisphere. Their community can be identified as the yellow smudge near the center of the image.

Swirls of green in Hubble's ultraviolet and visible-light view reveal hydrogen and sulfur gas that have been heated and ionized by intense ultraviolet radiation from the Trapezium's stars. Meanwhile, Spitzer's infrared view exposes carbon-rich molecules called polycyclic aromatic hydrocarbons in the cloud. These organic molecules have been illuminated by the Trapezium's stars, and are shown in the composite as wisps of red and orange. On Earth, polycyclic aromatic hydrocarbons are found on burnt toast and in automobile exhaust.

Stellar winds from clusters of newborn stars scattered throughout the cloud etched all of the well-defined ridges and cavities in Orion. The large cavity near the right of the image was most likely carved by winds from the Trapezium's stars. Located 1,500 light-years away from Earth, the Orion nebula is the brightest spot in the sword of the Orion, or the "Hunter" constellation. The cosmic cloud is also our closest massive star-formation factory, and astronomers believe it contains more than 1,000 young stars.

What a difference 11 billion years makes, as can be seen in these two comparative views of our Milky Way galaxy. The top view shows how our galaxy looks today; the bottom view, how it appeared in the remote past. This photo illustration is based on a Hubble Space Telescope survey of evolving Milky Way-type galaxies.
[Top View] — The current night sky is dominated by the white glow of myriad middle-aged stars along the lane of the Milky Way. Interstellar "pollution" from thick dust lanes can be seen threading through the long band of stars. They are interspersed with a few pinkish emission nebulae from ongoing star formation. Thousands of stars appear as pinpoints of light throughout the sky.
[Bottom View] — This is an imaginary view of our young Milky Way as it may have appeared 11 billion years ago, as seen from the surface of a hypothetical planet. The night sky looks markedly different than the view today. The Milky Way's disk and central bulge of stars are smaller and dimmer because the galaxy is in an early phase of construction. The heavens are ablaze with a firestorm of new star formation, seen in the pinkish nebulae glowing from stars still wrapped inside their natal cocoons. The handful of stars visible in the night sky are blue and bright because they are young.
The graphic of today's Milky Way was based on an all-sky image from Axel Mellinger and the Finkbeiner all-sky H-alpha survey. The illustration of the early Milky Way was constructed from the all-sky image from Axel Mellinger and Robert Gendler's image of the M33 galaxy. less

This undated composite image courtesy of NASA shows the distribution of dark matter, galaxies, and hot gas in the core of the merging galaxy cluster Abell 520, formed from a violent collision of massive galaxy clusters. The natural-color image of the galaxies was taken with NASA's Hubble Space Telescope and with the Canada-France-Hawaii Telescope in Hawaii. Superimposed on the image are "false-colored" maps showing the concentration of starlight, hot gas, and dark matter in the cluster. For decades, the strange substance called dark matter has teased physicists, challenging conventional notions of the cosmos. Today, though, scientists believe that with the help of multi-billion-dollar tools, they are closer than ever to piercing the mystery -- and the first clues may be unveiled just weeks from now. "We are so excited because we believe we are on the threshold of a major discovery," said Michael Turner, director of the Kavli Institute for Cosmological Physics at the University of Chicago, at an annual conference of the American Association for the Advancement of Science (AAAS) reported on February 18, 2013. = RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT " AFP PHOTO /NASA, ESA, CFHT, CXO, M.J.
